Optimization of NMR Data Utilization on Valhall - a Brown Chalk Oilfield
(Master thesis, 2015)The Valhall field started production in 1982 and has been producing since. A vast amount of data has been gathered and interpreted since then. Because of its complexity, there are still many questions left unanswered. Some ... -
Optimize Nozzle Based Inflow Control Devices at West Cable
(Master thesis, 2016)By evaluating the available inflow control equipment, results show that completing the well with a constant inflow cross-section area for every screen section along the horizontal well gives great results regarding increased ... -
Production Data Analysis During Transient Linear Flow in Shale Gas Reservoirs
(Master thesis, 2017)This work investigates the application of a graphical straight-line method often used to calculate the product of fracture half-length and the square root of permeability for hydraulically fractured shale gas wells. The ... -
Recovery Mechanisms in Naturally Fractured Carbonate Reservoirs: A Case Study of the Barents Sea Alta Discovery using Dual Porosity Model Simulations
(Master thesis, 2017)The Barents Sea Alta discovery consists primarily of fractured carbonate formations from the Mid-Carboniferous to Permian period. Significantly fractured reservoirs are subject to different recovery mechanisms than ... -
Reservoir Uncertainty Evaluation - A Producing Gas Field Case Study
(Master thesis, 2015)Once a field starts to produce, new information becomes available in terms of production data and measurements. By integrating this information to a reservoir model through a history matching process, an updated uncertainty ... -
Rock Physics Calibration for Ensemble Based 4D Seismic History Matching
(Master thesis, 2018)To model the future of a complex system, it is first necessary to be able to model the past. Accurate and efficient reservoir modeling is crucial for production forecasting and reservoir development. In this work the ... -
Same-Well Enhanced Oil Recovery (SWEOR) - Cyclic Hydrocarbon Production/Hydrocarbon Gas Injection in a Hydraulic Multi-Fractured Horizontal Well
(Master thesis, 2017)Unconventional reservoirs have gained big attention in the oil industry as these reservoirs constitutes huge amounts of hydrocarbon reserves. The required advanced production techniques as well as costs related to ... -
Shaly Sand Petrophysics and its Impact on Full Field Reservoir Simulation
(Master thesis, 2014)When a discovery has been made, appraisal wells are drilled, cored and logged. With the information they provide, an evaluation of the formation characteristics begin. Many parameters are correlated to the porosity log, ... -
Simulation of CO2 Injection in a Reservoir with an Underlying Paleo Residual Oil Zone
(Master thesis, 2018)Paleo residual oil zones (PROZs) are zones below the oil-water contact (OWC) that contain residual oil. These types of zones exist in many fields around the world, but is often given little attention, due to traditionally ... -
Simulation of Wells with Fishbones using ECLIPSE
(Master thesis, 2016)Fishbones is a new stimulation technology that aims to provide hydraulic fracturing like stimulation while also leaving the operator in full control of the stimulation process. The technology creates up to several hundred ... -
A Simulation Study of the Barents Sea Alta Discovery - Investigation of Optimal Recovery Method
(Master thesis, 2018)A re-occurring topic in the petroleum industry is to enhance the oil and gas recovery while optimizing the return of investment. Decisions related to field development are critical because most of the investments are made ... -
Simulation Study on Surfactant Flood Performance in a Segment of the Edvard Grieg Reservoir
(Master thesis, 2017)The purpose of the work done during this project is to provide an overview of the topic of Surfactant EOR and to evaluate the effect of a Surfactant flood on reservoir recovery in a segment of the Edvard Grieg field. The ... -
Simulering av gassproduksjon i kullreservoar i Eclipse 100 og Tempest MORE - Ei litteratur og casestudie av metanproduksjon i kullreservoar
(Master thesis, 2013)Det vart gjort ei litteraturstudie på gassproduksjon i kullag. Dette kan best forstås gjennom eit "dual porosity" system, der gassen er lagra i adsorbert tilstand i matrix i kullet og produseres gjennom sprekkesystemt til ... -
The Effect of Field Pressure Interference: A Simulation Study on Aquifer Modeling and the Effect on Small Oil Fields from a Common Aquifer - Applied to Trell
(Master thesis, 2017)Petroleum reservoirs do sometimes communicate through a regional aquifer. This means that a pressure drop imposed in any of the fields is transmitted across the aquifer to the other fields, and manifested as pressure ... -
The Effect of Small-Scale Heterogeneities on the Gas Distribution in the Tubåen Formation through Upscaling of CO2-Brine Relative Permeability
(Master thesis, 2017)The Tubåen Formation in the Norwegian Sea is an aquifer and was used by Statoil ASA as the injection reservoir for CO2 separated from produced gas at Snøhvit in the time period between April 2008 until it was abandoned in ... -
Using Microfluidics to Study the EOR Potential of Nanocellulose
(Master thesis, 2018)As many of the existing oil reservoirs show declining production, there is a need for research on enhanced oil recovery (EOR) techniques that can accelerate further production. The use of nanoparticles to enhance oil ... -
Water Alternating Gas in Stratified Reservoirs - A Sensitivity Study of WAG Parameters
(Master thesis, 2015)Water alternating gas (WAG) injection is an EOR method where water and gas is injected in cycles. The process exploits the microscopic displacement advantages of gas while using subsequent water slugs for mobility control. ...
